Trident Snorkeling and Scubadiving Mask Sealer

[chapa.r]

anyone use Snorkeling / Scubadiving Mask Sealer for leaks?

Some have mentioned doing so, but it is fairly uncommon.
My opinion is that a mask liner will silence minor leaks;
but big leaks mean the mask may be incorrectly adjusted or does not fit.
Too tight/old headgear may cause creases, resulting in excessive leaking.
